Current Best converter from a Latex source to Keynote with many equations

I am lost in front of the large number of converters from PDF to Keynote or to PowerPoint.

I don't want to convert a PDF to Keynote but I would like simply find an application that converts, as pretty as possible, a Latex source to a Keynote presentation.

Ideally, if the Latex equations from Latex source could be generated also into the Keynote presentation, this would be great (I mean, I can modify easily the Latex equations once the Keynote presentation is generated).

I am opened also for non-free applications, provided the result is pretty.
